Mal’ta MA-1 DNA

The origins of the First Americans remain contentious. Although Native Americans seem to be genetically most closely related to east Asians there is no consensus with regard to which specific Old World populations they are closest to. Here the authors sequence an ancient genome of individual (MA-1), from Mal’ta in south-central Siberia, to an average depth of 1x. Based on the author knowledge, this MA-1 DNA is the oldest anatomically modern human genome reported to date. I converted this raw sequence reads supplied in this scientific paper to formats familiar with genetic genealogists.
